Vegetable hide and seek

What vegetables do you hide in bolognaise or slow-cooked meals? Do you go for the same ones each time? Do you leave some slightly chopped (eg carrot, mushroom) so your children will just notice them or do you whizz them all?
Along with zucchini, carrot and mushroom, I have also included some grated beetroot (yes they notice the colour but the flavour isn’t dramatically affected), brussel sprouts and even kale.

Don’t be shy of trying new vegetables! These might be the ones you completely hide or for kale/spinach, I slice finely and then chop so there aren’t big, long ‘scary’ bits. If the boys notice it, I don’t pretend it’s not there and I don’t make a big deal. I might say ‘oh that’s just kale…gosh you’re doing a great job eating your dinner tonight’ or if they look terribly worried….well, at first I did say ‘it’s basil!’ as I know they eat that no worries. Once they were happy to eat it, the next time I was more confident to label it kale. The dark, leafy greens have so many health benefits…

Will you buy a bunch at your next shop to try? Or get some brussel sprouts to finely slice?
